A current-carrying conducting rod of mass m and length L levitates above the ground in the presence of a uniform magnetic field of magnitude B that points east. Note: You should take gravity into account in this problem.

Different units of length and mass exist. As for the unit of mass, it was defined as the mass of а cubic centimetre of water at the temperature of 4 degrees (the temperature of its maximum density).

So in this rod a compressive strain is developed and is given by Page 4 of 429. Chapter-1. the upper face of the element relative to the lower face and L is the distance between these faces.
14. As arule, if the length of a conductor is doubled, the resistance is doubled too. A red hot rod of steel would have burned brilliantly if it had been placed in the liquid air. Lately numerous applications of liquid air have been proposed and have been used in all branches of life.
We have two masses interconnected by a rod, and the assembly is moving at a certain velocity across a horizontal plane, in a direction perpendicular to the length of the rod.
A conducting rod of mass m and length lis placed over a smooth horizontal surface. A uniform magnetic field B is acting perpendicular to the rod. Charge q is suddenly passed through the rod and it acquires an initial velocity v on the surface, then q is equal to (a)  2mv/Bl
Put that right down over here, and we could say that the moment of inertia of a mass of a rod, it's rotating around its end, is always gonna be 1/3 m L squared. So 1/3 times the mass of the rod, times the length of the rod squared, which is gonna be the same as this R here, because this ball's line of closest approach was jus equal to the ...
( M = 3 kg , m = 2 kg, a = 60° . ) 18 m 1. IVlechanics Problems 1.2 Dynami cs Problem 79. A small cart of mass m is at rest on a horizontal track. A vertical column of length L = 2 m and the same mass m is fixed to the cart. A rod of the same mass m and length L = 2 m is attached to its upper end with a hinge, and released from a horizontal ...
R = 2-5 m at a given instant of time. The speed of the particle is (1) 4-5 m/ s (3) 5-7 m/s (2) 5-0 m/s (4) 6-2 m/ s . A rigid ball of mass m strikes a rigid wall at 600 and gets reflected without loss of speed as shown in the figure below. The value of impulse imparted by the wall on the ball will be 600 Two rotating bodies A and B of masses m

• A sign has a mass of 1050 kg, a height h = 1 m, and a width W = 4 m. It is held by a light rod of length 5 m that is perpendicular to a rough wall. A guy wire at 23 to the horizontal holds the sign to the wall. Note that the distance from the left edge of the sign to the wall is 1 m. See Figure 7.
• A conducting rod with a length ℓ = 25 cm is placed on a U-shaped metal wire that is connected to a lightbulb having a resistance of 8.0 Ω as shown in the figure. The wire and the rod are in the plane of the page. A constant uniform magnetic field of strength 0.40 T is applied perpendicular to and into the paper.
• A rod of length 1.05 m having negligible mass is supported at its ends by two wires of steel (wire A) and aluminium (wire B) of equal lengths as shown in Fig. 9.15. The cross-sectional areas of wires A and B are 1.0 mm2 and 2.0 mm2, respectively.
• A has mass m A, particle B has mass 2.00m A, and particle C has mass 3.00m A. A fourth particle D, with mass 4.00m A, is to be placed near the other three particles. In terms of distance d, at what (a) x coordinate and (b) y coordinate should particle D be placed so that the net gravitational force on particle A from particles B, C, and D is zero?
• Jun 09, 2019 · 42.A metal rod OA of mass m & length r is kept rotating with a constant angular speed v in a vertical plane about a horizontal axis at the end O. The free end A is arranged to slide without friction along a fixed conducting circular ring in the same plane as that of rotation.

A conducting rod of mass m and length l is placed over a smooth horizontal surface. A uniform magnetic field B is acting perpendicular to the rod. Charge q is suddenly passed through the rod and it acquires an initial velocity v on the surface, then q is equal to

15. If M is magnetic moment and B is the magnetic eld, then the torque is given by (a) (b) (c) (d) Correct: c 16. A copper rod of length l rotates about its end with angular velocity ω in uniform magnetic eld B. The emf developed between the ends of the rod if the eld is normal to the plane of rotation is (a) (b) (c) (d) Correct: b 17. would result in the greatest amount of expansion (∆L). a. Increase the temperature of a 5.0-m length copper rod from 50°C to 100°C. b. Increase the temperature of a 5.0-m length copper rod from 50°C to 200°C. c. Increase the temperature of a 10.0-m length copper rod from 50°C to 100°C. d.
